Swimming with sharks and stingrays in Caye Caulker island in Belize is one of the top 10 attractions from the country. Nurse sharks and huge manta rays chose this paradise as home. 
Belize is the only country inland from Central America that has english as main language and has a recent independence from United Kingdom in 1987. To reach the the island of Caye Calker you must take a two hour ferry from the maritime terminal in the capital Belize city.
Beside the island you have one of the biggest barrier reefs in the world with 3 snorkeling spots: Hol Chan Channel, Shark Ray Alley e Coral Garden.
The tour cost about 15 USD and incude equipment, boat ride and food. We started early in the morning fitted our fins and masks and got to a small boat into the ocean. After half an hour our first stop to do snorkeling. Shallow waters, a few corals and not that much maritime life.
Our second stop a surprise, tons of stingrays swimming around the boat. It is indeed a bit scary in the beginning because those fishes can easily kill a human with the sting. The guide asked us no to touch or disturb any of the and it would be fine. In this spot we also saw our first nurse-shark.
We entered the water a bit apreehensive but got used to them after a while. A guide from other boat made some demonstrations holding sharks and stingrays.
After this unique experience we headed back to the boat and ate a buffet of fruits.
